3-8-3. Network Ports
When you connect one or more DVRs to a network through an IP sharing device, each device must have a
unique TCP port number for access to each unit from outside the LAN. Also, the IP sharing device must be
configured for port forwarding so when each port is accessed on the IP sharing device, it will forward to the
appropriate DVR.
Note: This port number is listed next to the Port menu option in the Network Setup screen. If you plan to
access the DVR units only from within the same LAN, the TCP port does not have to be changed.
Note: Port Forward function will be supported to the next version.
